Did you go into the Office portal on the web? Should be able to get to it there.

I have two clients with this issue. Dont whatever you do attempt the online repair that Microsoft recommends. I tried that (could just be unlucky) but it got half way through then just said "something went wrong" and now the entire office suite home and business 2019 has just vanished off the computer.

Something went wrong alright.

I tried a complete reinstall; no help.

  It would appear the MS have starting fixing this and Outlook is working again on a few computers that were crashing.

Bdpoop I can verify this particular situation happens - it just erases everything. The only machines at work which will run Outlook at the moment are the ones with auto updates turned off. Frustrating doesn't begin to describe it.
